Hello team,

Is it possible to set different current (Analog Dimming) for each OUTx channel?

If not, could you introduce LED driver which can control each LED channel, and fulfill spec below?

Hi Kei,

What is the input voltage range required?

If combine the 4ch to 1ch, will the VLED then be 32V?

Hi Patrick-san,

The input voltage is 5V, and VLED is 8V.

Customer don't want to combine 4ch to 1ch.

Customer just want to know, if they can adjust the analog dimming for each channel.

Hi Kei,

TPS92390 doesn't support individual analog current control. May I know what is this project schedule?
